What is the minimum amount of hens per roosters so that the roosters won't fight each other?

[Sire12]

I've read that as a rule of thumb 1 rooster per 10 hens seems to be the sweet spot, I currently have 1 rooster and 5 hens and they're happy enough they have huge big yard to free range in all day and I'm planning on hatching out some eggs in an incubator and keeping 1 of the hatched roos, they're all brahma breeds so they're mostly docile anyway but how many hens per roo would keep them all fairly content and happy?

I think you have the answer. About 10/1. That would keep the roosters plenty busy.

It really depends on the roosters.
I have one rooster and one cockerel.
I have 10 hens and 14 "of age" pullets.
The rooster still runs off that cockerel every chance he gets if he sees him mating any of the girls.

I do not think there is a magic number. It’s going to depend on the breed, age and the roosters and hens involved, how much space they have And careful observation on your part. Don’t just watch for the roosters to get along but also for stress or injuries to the hens from over breeding.

The idea of 10:1 ratio is to lessen the stress between all the birds. Boys have options for mating and can care for his ladies, and there are enough ladies so that one isn't being over-mated.

But it also depends on breed and individuals.
There is not an exact answer.

It really doesn't work this way. The rooster will have his favorites and they will always show signs of wear.
As stated above, I have two breeding males with 24 breeding females. I have three hens with small bare spots on their backs from being mated more frequently by the rooster as he prefers these girls.
The 10:1 ratio often quoted as being "ideal" is to ensure all hens are fertile in breeding programs. It doesn't really have anything to do with having enough hens for each rooster so the roosters don't fight.
Having enough territory so they can each have their own space with the hens that have chosen them will go a lot further in reducing fights as well as the temperaments of the boys involved.
Young males raised in an adult flock will also learn the ropes better so raising the son of a good rooster within the adult flock improves the chances of success. Having that son broody raised would be ideal.

I didn't state it properly, but I meant that the ratio stands partly becauze if you have a few females and two or more males, the females are likely to be over stressed and over mated.
Roos like protecting a flock and having his choice of females. I understand favoritism, and rearing a young cockerel but there still needs to be more hens than roos.
The OP very well could have a hatch and be fine. Depends on a lot of factors.

No.
The 'rooster' to hen ratio of 1:10 that is often cited is primarily for fertility efficiency in commercial breeding facilities.

It doesn't mean that if a cockbird has 10 hens that he won't abuse or over mate them.

Many breeders keep pairs, trios, quads, etc

It all depends on the temperaments of the cock and hens and sometimes housing provided.

Backyard flocks can achieve good fertility with a larger ratio.

I have read many things come into play when having multiple roosters. Raising them together from the time they hatch, getting all docile breeds, having enough space, and having enough hens. You don't want too few hens with a Rooster anyway they will get over bred and have wounds on their backs. I have 4 Roosters in my mixed flock of 33 chickens. I originally ordered 3 Roosters 1 Black Jersey Giant, 1 Buckeye, and 1 Lavender Orpington. I accidently ended up with a Midnight Majesty Marans Rooster who was supposed to be a Pullet. he is my Avatar picture. My pullets are MMM, Black and White Jersey Giants, Lavender and Buff Orpingtons, Easter Eggers, Calico Princess, Dominique, Speckled Sussex and Buckeyes. They are 4 months old right now, my Cockerels are all crowing, my MMM Cockerel just started chasing the ladies but they have nothing to do with him. 3 of my hens are laying small eggs. So far they all get along great. I have never seen an all out fight with any of my birds. Just a little bit of chest bumping on occasion and that almost never happens any more. They have never been aggressive with me, but I spend a lot of time with my birds and I do hold my Cockerels on occasion. I am hopping that they stay friendly, only time will tell.

Good luck with your flock!
If the cockerels all get along, you probable have a good thing going between your girls and boys!
